Silicified bryozoans in chert nodules derived from the Kaibab Formation are apparently all from facies 1 of the Beta Member. The bryozoans are a typical Permo-Carboniferous assemblage of stenoporid trepostomes, fistuliporid cystoporates, fenestrates, and rhomboporid cryptostomes. Taxa included are in the genera ?Stenodiscus, Fistulipora, Meekopora, Fenestella, Bicorbis, Rhabdomeson, Streblotrypa, and Girtypora (G. maculata, n. sp.). Bicorbis is known only from the Kaibab and equivalent strata... Topics: Bryozoa, Fossil, Paleontology -- Arizona Grand Canyon, Paleontology -- Permian

Diverse and abundant fenestrate bryozoans occur in two Lower Devonian levels of reefal and perireefal limestones of Central Bohemia, within the type area for the Lower Devonian stages. The reefal deposits of the Koneprusy Limestone (Pragian) are characterized by greater abundance and diversity, with 29 species. A less abundant and, in large part, different fauna of 17 species is found in perireefal and basinal deposits of the younger Zlichov Limestone (Zlichovian). The two faunas have high...
